Technical description


(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.

Technical description


The remontoire (constant force device) comprises a secondary wheel (1) assembled on a lever (2), which swivels concentrically to the cage (3) of the tourbillon. This lever stops the principal wheel which carries the second hand (4) and transmits the energy of the barrel, whereas the auxiliary spring (5) (or equalizing spring) gives its energy to the escapement. (6) This then allows the secondary wheel to release once per second, and with repetition, the auxiliary spring is re-fuelled by the principal wheel.

What is a remontoire ?
In the Toubillon Souverain, the remontoire - a constant force device - can be compared to a dam that controls the flow of water and provides constant energy to the blades of a turbine. In effect, the remontoire regulates the power to the escapement to attain greater stability in rate. The adjustable inertia weights make it possible to optimize the amplitude of oscillation; the four-armed balance beats at a frequency of 21'600 v/h.

Technical description


(1) Pinions to adjust distance
(2) Adjustable inertia weights
(3) Special balance

François-Paul Journe pays tribute to the research conducted on resonance by the great 18th century watchmakers, with the presentation of the first wristwatch resonance chronometer.

In 1983, François-Paul Journe took up the challenge with a first creation in the form of a pocket-watch, which did not yet perform according to his expectations. It would take fifteen more years of work for the watchmaker to gain the maturity and the experience to enable him to present an exclusive world première, the first resonance wristwatch.

Technical description


(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.

(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.

Technical description


The remontoire (constant force device) comprises a secondary wheel (1) assembled on a lever (2), which swivels concentrically to the cage (3) of the tourbillon. This lever stops the principal wheel which carries the second hand (4) and transmits the energy of the barrel, whereas the auxiliary spring (5) (or equalizing spring) gives its energy to the escapement. (6) This then allows the secondary wheel to release once per second, and with repetition, the auxiliary spring is re-fuelled by the principal wheel.

What is a remontoire ?
In the Toubillon Souverain, the remontoire - a constant force device - can be compared to a dam that controls the flow of water and provides constant energy to the blades of a turbine. In effect, the remontoire regulates the power to the escapement to attain greater stability in rate. The adjustable inertia weights make it possible to optimize the amplitude of oscillation; the four-armed balance beats at a frequency of 21'600 v/h.

(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.

The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.
The Octa Automatique (made from 2001 to 2016) emblematic timepiece is the first automatic watch made by F.P.Journe.

A 38 mm STEEL CASE FOR 5 EMBLEMATIC F.P.JOURNE WATCHES

« The Historic Size »

In the 1980’s, François-Paul Journe constructed custom-made pocket watches for very discerning collectors. In 1991, he presented his first wristwatch at BaselWorld with a Platinum case of 38 mm in diameter. This was unheard-of at the time, when watches ranged between 33 and 36 mm maximum for the largest ones.

The main reason the watch was so large was that it was the first Tourbillon wristwatch with Remontoir d’Egalité ever created, and the complex mechanism took up a certain amount of space.

In 2001, F.P.Journe presented a new Tourbillon in a limited series of 99 pieces. This was the start of the Ruthenium Collection: a collection of 5 models, all with a case that was 40 mm in diameter. From then on, each watch could be offered either in 38 or 40 mm.

The Grande Sonnerie, presented in 2006, was 42 mm in diameter. After that, collectors began requesting 42 mm watches. But in order to maintain harmonious proportions, the dimension of the dial had to be completely redesigned as well as the complication that would animate the watch.

Thus, the Chronomètre Optimum, which is a compendium of chronometric savoir-faire, naturally required more space. A 38 mm case is too small; 40 or 42 mm sizes would suit perfectly this watch’s incredible mechanism.

Afterwards, the Quantième Perpétuel with instant jump and the Octa Lune were also adapted to 40 and 42 mm cases to make their indications more legible. Now, wishing to celebrate the end of the historic 38 mm case after 25 years of existence, F.P.Journe has created 38 exclusive collector’s sets containing 5 emblematic and historic watches in 38 mm.

38 mm in Steel!
It is extremely rare for luxury watches to be cased in Steel. There are very few such watches, and they reach much higher prices at auction than the same models in precious metals. This set is intended for true collectors, those who know what is rare. The combination of 18K rose Gold movements with 38 mm Steel cases makes this set the rarest of all F.P.Journe’s collections.

5 Watches!
The Tourbillon Souverain (made from 1999 to 2003) was never made with a Gold movement, which makes it doubly exclusive.
The Chronomètre à Résonance in its original configuration (made from 2000 to 2009) with 2 symmetrical analog display dials.
The Octa Automatique (made from 2001 to 2016), emblematic timepiece, is the first automatic watch made by F.P.Journe.
The Octa Calendrier, (made from 2003 to 2015) the company’s automatic bestseller since its creation.
The Chronomètre Souverain (made since 2005) had to be included in the set, due to its aesthetic purity and its magnificent mechanism; pure minimalism.

Technical description


(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.
